PRODUCT TYPES RELEASED FOR THIS ARCHIVE: ChemCam RDR
PRODUCT TYPES UPDATED FOR THIS ARCHIVE: ChemCam BROWSE
This release includes new products from Sols 360 through 449.
Some of the RMI Browse data for sols 13 through 359 were updated to correct
the target names which were incorrect initially.
Two RMI labels have known errors, which were propagated from errors in the
EDR labels. The keyword EXPOSURE_DURATION_COUNT contains a value
of "-5,536" which is lower than the acceptable minimum of "0". The error is
understood and will be fixed in release 6.
Values for INST_CMPR_RATE and INST_CMPRS_RATIO for some RMIs are incorrect due
to a bug in the EDR label generation code. This error was propagated to the
RDRs. There is a fix but OPGS wants to do further testing, so the products
will be corrected in a later release.
Several products have been removed from the archive because the ChemCam Team

PRODUCT TYPES RELEASED FOR THIS ARCHIVE: ChemCam RDR
PRODUCT TYPES UPDATED FOR THIS ARCHIVE: ChemCam MOC CSV and LBL files
sol 13-234
This release includes new products from Sols 271 through 359, and revised
product labels from Sols 13 through 234.
The algorithm for computing the MOC files has been changed. All files have
been reprocessed using the new PLS1 algorithm substituted for PLS2 (see
CAM_LIBS_RDR_DS.CAT)
The Browse data for sol 13 through 176 and 192 have also been updated. The
previously released files did not have the correct target name on the file.
The ChemCam LIBS EDRs for sol 30 have been reprocessed, but the corresponding
RDRs are still not reprocessed. They will be included in the next release.
One additional caveat should be noted in addition to those given in Release 1:
8. Major element totals on some samples exceed 110 wt % (100% + RMSEP).
These are typically found in observations rich in Si, Al, and alkalis. We are
investigating this issue, but for now these data should be ignored.
RELEASE NUMBER: 3

This release includes new products from Sols 181 through 269, and revised
product labels from Sols 13 through 176.
All ChemCam CL5 RDR label (LBL) files from Sols 13 through 176 have been
revised and re-released to correct the LMST and SCLK times. Only the label
files have been changed. The data files have not been changed. It was
discovered, too late for this release, that some of the target names in the
RMI and most of the LIBS Browse files were incorrect. They will be corrected
in Release 4.
ChemCam LIBS EDRs for sol 30 have been reprocessed, but the corresponding
RDRs have yet to be reprocessed. They will be included in the next release.

not processed correctly and will be delivered in MSL Release 3.
RELEASE NUMBER: 1
RELEASE DATE: 2013-04-10
DATA COVERAGE: 2012-08-16 to 2012-11-05 (Sols 10-88)
PRODUCT TYPES RELEASED FOR THIS ARCHIVE: ChemCam RDR
PRODUCT TYPES UPDATED FOR THIS ARCHIVE: None
NOTE:
ChemCam LIBS RDRs for Sols 0-9 are not released due to processing errors.
They are being reprocessed and will be included in Release 2, June 6, 2013.
No ChemCam data were acquired on Sol 89.
The Data Product SIS (file MSL_CAMERA_SIS.PDF) contains some typographical
errors that will be corrected in a future release.
Several caveats should be noted in the first submitted data:
1. Each observation represents a small region 350-550 um in diameter, not
a whole-rock composition.
2. Results may vary with depth. Significantly heterogeneous observations in
z should be flagged in the data. Individual shot data are available from the
ChemCam team.
3. Results should be within the stated (root mean square error product) RMSEP
uncertainty in most cases, e.g., in which the standards used in the training
set (Wiens et al., 2013) are relatively representative of the samples. Do not
trust the MOC results for compositions that are outside the compositional
range covered by the training set.
4. Major element oxide totals appear to be reliable except in cases of high
SiO2, in which case the totals increase to > 100% In these cases, the user
may wish to re-normalize the major elements to 100%.
5. Samples with the highest SiO2 do not have good correspondent
representation in the training set (see note above) and their compositions
should be treated with caution.
6. Likewise, samples with > 4% Na2O or K2O do not have good representation
in the training set and should be treated with caution. In these samples
the alkalis will be underestimated.
7. Titanium appears to be underestimated in many cases and might be useful
more for relative scale rather than for absolute composition.
We expect to reprocess the Level 2 (MOC) data, substituting PLS1 for PLS2
for at least some of the elements. As described in Wiens et al., 2013, this
allows optimization of the number of principal components used for each
element, improving the values and reducing the RMSEP by 10-30% relative to
current RMSEPs.
Concerning RMI products, the following caveats should be noted in the first
submitted data:
1. The RMI flat field was derived from the sum of two sky images taken on
Sol 32. The EDR files of these sky observations are:
CR0_400349083EDR_F0040000CCAM05032M1.IMG, and
CR0_400349161EDR_F0040000CCAM05032M1.IMG; The mast was pointing straight up
(85-deg. elevation) and was rotated in azimuth by 180-deg. between the two
images. The processed RDR images have been corrected for this flat field.
2. The processed images have also been corrected for non-linearity at high
intensities (high digital number (DN) levels). A preliminary correction table
has been derived from a dedicated test conducted on Sol 131. It gives
satisfactory results for signal levels below 1500 DN, and this correction will
be refined in the future.
3. The quick-look products archives in browse show the expected location of the
laser pit with a red cross at the center of the image. The temperature given in
the caption is the temperature of the telescope and not the temperature of the
camera. The scale is is given as the width of the image in centimeters,
assuming a field-of-view of 20.3 mrad for the distance-to-target given in the
caption.
******** SECTION B ********
This section is provided for general notes concerning the archive as a whole.
1. The product version number is the ChemCam team's processing version, and the
archived product may have a version number greater than 1.
2. Some documents in this archive appear in Portable Document Format
(PDF) files. PDF files can be read using free software available at
www.adobe.com. PDS requires that a PDF document be accompanied by an
ASCII text version; however, this has not been done for some PDF files
in this archive because the documents contain figures, tables,
equations, or other content that cannot be rendered as ASCII text. HTML
is sometimes used as an alternative to plain ASCII, but in this case
suitable HTML versions that captured all the content of the PDF could
not be created.
3. A subset of ICER-compressed ChemCam RMI data products since landing
(Releases 1-16) may be incorrectly marked as LOCO compressed in the
INST_CMPRS_NAME keyword under the COMPRESSION_PARMS groups. The correct
compression algorithm used can be determined by looking at the
TELEMETERY_SOURCE_NAME keyword for 'Loco' or 'Icer'. In situations where
the compression algorithm is incorrectly identified the keyword values in
the COMPRESSION_PARMS group are incorrect.
4. August 8, 2018: 512 products in the archive were identified as
either duplicates or invalid data that were delivered in error, and
that were residing in the wrong subdirectories based on their sol numbers.
